Caught By .Net!

Just my first Flex test, I wrote two simple methods in the asp.net webservice page.

Some key points I learn from this practice:
1. Call and bind webservice.
2. Fire event after webservice loaded. ( <s:CallResponder id="HelloWorldResult" result="WSLoadComplete(event)" />)
3. Redirect to other page ( navigateToURL(new URLRequest('../default.aspx'),'_self'))

here is the MyFirstFlex.mxml:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark"

               xmlns:testwebservice="services.testwebservice.*" 
               creationComplete="application_creationCompleteHandler(event)">
    <fx:Script>
        
        <![CDATA[

            {
                TestArraryResult.token = testwebservice.TestArrary(txtName.text);
                //ddlDropdown1.dataProvider=
            }
            
            
            protected function btnHello_clickHandler(event:MouseEvent):void
            {
                HelloWorldResult.token = testwebservice.HelloWorld();
                //HelloWorldResult.addEventListener(

            {
                lblTest.text="Load Completed";
            }        
            
            
            protected function application_creationCompleteHandler(event:FlexEvent):void
            {
            //    HelloWorldResult.token = testwebservice.HelloWorld();
            }

            {
                // TODO Auto-generated method stub
                navigateToURL(new URLRequest('../default.aspx'),'_self')
